我们读了您刊1978年4月号“膀胱气钡双重对比造影初步报告”一文后有如下看法和作者商榷。膀胱气钡双重对比造影国外早在50年代末和60年代初即有所报道,它的适应症范围很狭小,但有时并发症却比较严重,如发生空气栓塞、逆行感染等。因此,后来采用的就较少。这种检查方法对于膀胱镜检查有困难(如膀胱肿瘤较大,膀胱镜检查看不到全貌时)或不能进行膀胱镜检查的患者才有一定的价值。如果肿瘤或膀胱内病变较小(如输尿管口较小囊肿)膀胱镜检查又无禁忌时,就没有气钡造影的必要,尤其是对有膀胱颈部梗阻的前列腺增生 We read your article in 1978 April “double contrast air bladder imaging contrast report” after the article the following views and the author to discuss. Bladder double contrast barium contrast as early as the late 1950s and early 1960s has been reported that its range of indications is very small, but sometimes more serious complications, such as the occurrence of air embolism, retrograde infection. Therefore, less used later. This screening method for cystoscopy is difficult (such as large bladder tumor, cystoscopy can not see the whole picture) or can not be cystoscopy patients have some value. If the lesion in the tumor or bladder is small (such as ureter orifice less cyst) cystoscopy and no contraindication, there is no need for barium radiography, especially for bladder neck obstruction of benign prostatic hyperplasia
